Aside from being self-hosted how does this differ from +suffix Gmail addresses?
n.ame@gmail.com or nam.e@gmail.com . Many SMTP servers respect periods as differentiating emails, so services can't delete them. It doesn't help you stop spam, but you can add a gmail filter that n.ame@gmail.com is put in a separate label. And it's very fast to type, easy for non tech-y people
So far the most spam I’ve gotten has been to the address I used for Amazon (probably leaked by a third‐party seller there).
I mean you can pick any format you want before the "@", but yeah my format is trivial. Nobody has tried to do it automatically yet though, as far as I can tell.
For example, to enable plus addressing in postfix is only a matter of defining:
recipient_delimiter = +
Though I had originally made this because with the "+" approach, you can easily get the original address by simply removing everything after the "+", while with mine you cannot. On top of that, sometimes "+" does not work in services that do "strict email validation".
One never let me change my email or password when I used the +.
OP also could have just used a regex in the virtual file.
